I am new to paintballing and new to this forum, and I need your help. I have a stock 2001 or 03 xtra, one of the first models, and Iím looking to severely upgrade it. I have read tons upon tons of forums about etriggers and barrels and hoper and what not. But I need a final opinion and what better place to look than here. so help me out below Iím making a list of the upgrades I want to make, feel free to copy and paste it into your reply and just write across from it. Thanks a lot for your help.

Bolt:
Barrel:
Hopper:
Electronic upgrade:
Trigger:
And any other ideas you might have:

Bolt: new bolts arent that necessary
Barrel: CP one piece .685
Hopper: used Reloader B
Electronic upgrade: the CAMD eframes are nicer than the old LED ones. either way if you get one of those and not the new style you may need a new rechargeable battery.
Trigger: it's personal preference but any with a bearing will be good
And any other ideas you might have: a newer body so you can put a clamping feedneck on it. you can find used ones pretty cheap. oh and uprgade to HPA. Also, a spring kit, high flow valve, regulator

as long as you can still cock the bolt you should be able to use it. all are pretty much the same other than how the bolts cock (to the side, to the top, out the back, etc) you would pretty much have to buy them used. with all this money in it though you might as well save up for a used nicer marker
